This article aims to provide an overview of all you need to know about the NotPetya Ransomware with details regarding how it works, how to recover data in the event of an attack and also some very useful tips on how to prevent an attack.
What Makes Notpetya Ransomware Unique?
Usually, hackers design ransomware to extort victims before releasing their files but NotPetya doesnt follow this trend. This ransomware is simply created to thrash out and destroy systems. Although it was initially designed to demand a $300 bitcoin payment, this quickly disintegrated. This made things quite obvious that it was not about the money as every other aspect had sophisticated programming.
Another unique thing about NotPetya is the way it propagates across a network. You should continue reading to find out how this ransomware spreads once a host computer is infected.
How does the Infection Spread?
This malware is considered very dangerous mainly because it requires hardly any human intervention to spread. How then does it spread? The Notpetya virus spreads on its own. While the original Petya virus required its victim to unwittingly download it from a spam email, launch and grant it admin permission, the Notpetya doesn’t need human intervention to encrypt files. The Notpetya malware uses AI to spread from one computer to the other.
The first infection vector seemed to have been via a backdoor in an accounting software, the ME Doc, that is used by a lot of companies in Ukraine. Using a variety of techniques after infecting computers from Medocs servers, the Notpetya virus spread to other computers including two exploits developed by the United States NSA to take advantage of a flaw in windows implementation of the SMB Protocol, the Eternalblue and Eternalromance.
Similarly, Notpetya can also take advantage of the Mimi Katz to find network administration credentials in the infected computer’s memory. It subsequently makes use of the PsExec and WMIC tools built into Windows to remotely access other computers on the local network and get them infected as well.
Like its predecessor, the Notpetya virus forces the victimized Windows users to pay a digital ransom through Bitcoin in return for their data. However, it attacks a part of the operating system, the Master File Table (MFT) and does not encrypt files on computers. This then overwrites the Master Boot Record.
What’s worse, NotPetya encrypts everything. The NotPetya malware goes way beyond its predecessor the Petya’s trick of encrypting the master boot record. Notpetya ensures it goes after all files to seriously screw up your hard drive. The system set-up for receiving ransom payments also disintegrates rapidly. This leads experts to believe that it was never designed for the money.
This peculiar behavior of Notpetya has lead experts to believe it is more than a ransomware and can only be developed by a creator with large resources at its disposable. The Notpetya seems similar to its predecessor at first glance with the demand for a ransom in exchange for a key to decrypt. But, the victim doesn’t send his unique identification which means a key generated could maybe not be his and all files could be summarily lost.
How to Recover Data After a Notpetya Ransomware Attack
